All deficient items identified during the commissioning process were documented and tracked regularly and re-inspected following corrective action. As a result, HEA’s commissioning process identified over 300 deficiencies. Examples of how the commissioning process improved equipment performance and overall occupant comfort include:
- Several air conditioning units were installed without local controls and could not be operated as per design intent. HEA advised and provided comments to new controls submittals
- Multiple packaged terminal air conditioner deficiencies were found during testing. HEA and Brookfield met and discussed proper systematic start-up and deficiency re-inspection. Upon review, deficiencies quantity was reduced during functional testing
- During balancing it was observed that the exhaust air system was not operating as intended. Consistent air flow regulator dampers were found to be missing/installed incorrectly, causing flow issues in respective ductwork
Project – The Knickerbocker

Major findings include the following:
- All base building and back of house air conditioning unit’s fans, coils, dampers and filters were found to be dirty. This affects the efficiency of the unit and in turn causes the building to use more energy to satisfy its heating and cooling needs.
- Some tenant packaged terminal air conditioners (PTAC) unit steam traps were found failed. This prevented the units from providing heat to the spaces that they served.
- The majority of lighting in the common spaces was found to be 60 W Candelabras and Linear Fluorescent T8s. This type of lighting is out of date and uses more energy than modern fixtures. By implementing lower wattage LED lighting, the building will save electrical energy.
HEA was able to identify numerous energy conservation measures and retro-commissioning measures that, if implemented, would over $9,000 per year in energy costs.
Project – One Blue Slip, Greenpoint Landing G1
Brookfield Properties contracted HEA to provide commissioning services for the Greenpoint Landing G1 project, also known as One Blue Slip. One Blue Slip is a 29 story residential building located in the Greenpoint neighborhood of Brooklyn. The building is approximately 360,000 sf; it is comprised of 359 apartments, and 10,000 square feet of amenities space.

HEA’s services included, but were not limited to completing LEED Energy and Atmosphere pre-requisite 3 for Fundamental Commissioning and EA credit 3 for Enhanced Commissioning. Specifically, HEA reviewed Mechanical, Electrical, Plumbing (MEP) designs and construction submittals; conducted installation inspections, pre-functional, and functional testing and provided a Systems Manual and Commissioning Report.
HEA worked with Turner Construction, the sub-contractors and Brookfield Properties through the duration of the project to ensure that the expectations for commissioning requirements were communicated properly; to this end HEA led commissioning meetings periodically at the onset of the project and then on a weekly basis during the functional testing phase.
The G1 Tower was certified LEED Silver by the USGBC.
Project – The Epic
Built alongside the existing St. Francis of Assisi Friary, this new LEED-registered, mixed-use rental apartment tower comprises 460 luxury residential units. It rises above a five-story podium providing 41,000 sf of space for St. Francis of Assisi, a new 77,000 sf headquarters for the American Cancer Society, and nearly 5,000 sf of ground-level retail space.
HEA commissioned the mechanical, electrical and plumbing systems, and produced a Measurement & Verification Plan. The plan was developed to identify significant changes to any energy consumption throughout the life of the building. This information provided the owner with the capabilities of monitoring energy consuming factors, identifying ways to lower energy and water consumption, thus improving overall functionality. The Plan will ensure the facility will remain as energy efficient in future years as it is when turned over.
Project – University Residence Halls
Due to growth at Missouri University of Science & Technology, HEA was contracted for a two-phase project at two residence halls. Retro-commissioning services were provided on the mechanical system of the first floor office area in Residence Hall I, or Residence College. After a year, it was observed that the air handling unit was not performing. HEA performed testing, identified the issues, and made recommendations that resulted in resolution and specified system performance.
Residential College houses 250 residents as well as two large meeting rooms, computer lab and laundry facilities. HEA also provided commissioning services on the mechanical and electrical systems in the new 80,400 square foot Residence Hall II/III. The facility will have four floors with 276 beds in a mix of four-person double semi-suites, and single rooms for resident advisors.

Project – Hershey Student Homes
Milton Hershey School is a cost-free, private, coeducational home and school for children from families of low income, limited resources, and social need. Students live in large, comfortable homes with 10 to 14 students in their own age group. A pair of married house-parents oversee each home, providing the structure that children need and take an active interest in their development.
Commissioning services were provided on behalf of the school for the design and construction of Wave III, ten new student homes and Wave IV, nine new student homes, including the full scope of mechanical, electrical, fire protection and plumbing systems. HEA evaluated the installation process, witnessed the proper start-up of all equipment, and performed pre-functional and functional tests on all systems.
Project – The Verdesian
Among this new luxury apartment building’s many environmental features is a system that conditions fresh air, exceeding New York City energy efficiency standards by nearly 40%. A natural gas microturbine produces 70 kW of power, or 20% of the base load, while recapturing enough bi-product heat to generate 100% of the domestic hot water. Overall the building lowers peak electric demand by 65%.
The LEED registered building is linked to a nearby black water treatment plant which recycles water from bathrooms and kitchens to re-supply toilets and provide make-up water for the cooling tower. The building also harvests rainwater and can store 10,000 gallons of recycled water for irrigation of the green rooftop garden. HEA performed commissioning services in conjunction with the USGBC LEED rating system, as well as conducted air quality sampling.
Project – Tribeca Green
New 26-story, 357,000 sf luxury apartment building achieved LEED Gold certification. HEA performed commissioning services in conjunction with the USGBC LEED rating system. The LEED commissioning process was tailored to satisfy environmental requirements of the Battery Park City Authority.
